ProCell - Process Flow CellsEnabling continuous online spectroscopic analysis in the UV/Vis and NIR
Modern process control benefits from access to
real-time information. Fiber-optic coupled
process flow cells are a key enabling technology
to facilitate the acquisition of continuous online
UV/Vis and NIR spectroscopic absorbance
process measurements. In many instances, this
allows the user to achieve significant cost savings
through process optimization. Process flow cells
contribute to plant safety by eliminating the need
for the extraction and transportation of potentially
hazardous process sample to a site laboratory
for analysis. Further advantages include a
possible reduction in the cost of process
sampling, and elimination of sample wastage.
With state of the art design and material
modeling tools, and over 15 years of process
application experience to draw from, Specac's
range of process flow cells have a proven track
record of reliability and robustness to ensure
long-term operation in the most demanding
industrial environments. Computer-aided optical
design ensures that our process flow cells have
the highest levels of optical throughput to ensure
the best quality of spectroscopic data.

Tailored to meet your needsMaterials, pathlength, interfacing: Your choice.
Specac process cells are customized to ensure
exact matching with the client’s process
requirements. Material metallurgies, seal types,
and window materials are chosen to be
compatible with the chemical and environmental
needs of the application. Optical designs are
configured for the UV/Vis or NIR spectral regions
as appropriate, and optical pathlengths are set to
ensure optimum spectral absorbance of the
target chemical species. A range of pipe fittings
and flange connections are available to interface
the process flow cell with the process pipe work.
Cleaning ports and seal leak warning ports can
also be integrated into the cell design.
Specac's application engineers work closely with
the customer to ensure the optimum process
flow cell solution for the application.

Specac | ProCell - Process Flow Cells
Light is transmitted via an optical fiber cable from
the spectrophotometer source to one port of the
process flow cell. Collimation optics then direct
this light beam through a set pathlength of
process stream to a second set of optics which
re-focus the beam to a return optical fiber cable
attached to the second process flow cell port.
The return optical fiber cable serves to transmit
the light beam back to the spectrophotometer
detector. Process flow cells are typically installed
as part of the process circuit either directly in the
process stream or as a “by-pass loop”. By
adopting the process flow cell in a “by-pass loop”
configuration, the user has the opportunity to
isolate the process flow cell from the process cell
for routine cleaning, servicing, or calibration.

Specac ProCell process flow cells are compatible
with a range of optical fiber cables, with core
sizes of up to 600 microns diameter. These
should be selected by the user to be appropriate
for the application. For instance, water-free
optical fiber is typically used for NIR applications,
while special UV-grade optical fiber should be
used if enhanced UV transmission is needed.
Optical fibers should also be appropriately coated
for the temperature experienced at the point of
connection to the process flow cell: polyimide-
coated or metal-coated fibers are recommended
for higher temperature applications. Specac
follows the industry standard by using the widely
available and popular SMA 905 style of fiber
connector to interface
optical fibers with the
process flow cell.
Optimized construction materialsRugged. Robust. Reliable.
Optical fiber cablesDelivering light to the point of measurement.
Process flow cells are designed to withstand the
rigors of process and environmental conditions
while maintaining continuous measurement
stability. The choice of construction materials is
an important consideration to ensure material
compatibility with a range of substances in the
process stream, and durability to the temperature
and pressures of operation - this often goes
beyond standard operating conditions, and
includes aggressive cleaning regimes and
extreme weather conditions.
Cell body material:
Specac ProCell process flow cells are
manufactured from a range of materials, chosen
to ensure optimum chemical compatibility and
environmental durability. Typical materials include
Stainless Steel 316L, Duplex Stainless Steel,
Hastalloy© C276, Zirconium, or Titanium, but
others are available upon request.
Window material:
Sapphire windows are used as standard to
ensure the highest level of process cell durability.
With outstanding thermal characteristics, coupled
with exceptional abrasion resistance – second
only to diamond – and strongly resistant against
corrosive process fluids, sapphire is a clear
material of choice for process flow cell windows.
Standard sapphire substrates offer excellent
transmission characteristics from the UV to 5
microns; for specific UV applications, UV grade
sapphire is available. As sapphire is able to be
polished to a high degree, it is less prone to
fouling than other lesser materials.
Seal material:
Process flow cells contain a seal between the
optical and mechanical components, and the
integrity of this seal is often critical to the reliability
of the cell. Specac offers a wide variety of seal
options to meet a broad scope of customer
needs. These include chemically inert perfluoro-
elastomers (such as Kalrez© or Chemraz©), or
gold diffusion bonding for the most demanding
applications.
For added peace of mind, perfluoroelastomer
seals may be incorporated in a unique dual seal
arrangement to guard against the unlikely event
of window seal failure. With the aid of complex
modeling software, Specac application engineers
can predict the behaviour of the seal under a wide
variety of conditions that may be experienced
during its lifetime.

Added featuresTell tale leak ports, fiber termination hoods, cleaning ports.
A wide range of added features are offered by
Specac to further enhance the performance of
our ProCell process flow cell product range.
For instance, seal leak warning ports can be
incorporated for additional process security, and
cells can be specified with a cleaning port to allow
easy in-situ cleaning of the windows without the
need to remove the cell from the process
environment. Furthermore, protective metal
hoods (to I.P. 65 rating) can be fitted over the
fiber connections to relieve strain from the fiber
connector, to guard against accidental damage
at the process cell port, and prevent ingression
of moisture and dust/dirt.
Range of Process CellsLiquids. Vapours.
ProCell Vortex Liquid Phase Process Flow Cell:
Specac's ProCell Vortex liquid phase process cell is
designed to sample industrial liquid streams by
means of UV/Vis or NIR. These applications
usually involve optical pathlengths of 1.0 - 10mm.
Typical specifications are 0 to 400°C and vacuum
to 1500 psi.
ProCell Typhoon Gas/Vapour Phase Process Flow Cell:

designed to sample industrial gas / vapour phase
streams by means of UV/Vis or NIR. The gas or
vapour stream is sampled through a preset, fixed
pathlength (20, 30, and 50 cm available as
standard), and typical specifications are 0 to 280°C
and vacuum to 1500 psi.

ProCell Vortex:
Tailored for the application
The ProCell Vortex series process cell is
designed to be flange mounted directly into the
process stream or in a by-pass. To ensure ease
of process integration, the cell can be configured
from a wide range of ANSI and DIN flange sizes.
A choice of cell body materials, typically starting
with Stainless Steel, Duplex Stainless Steel, or
Hastelloy®, and a selection of high performance
perfluoroelastomer window seals or dffusion
bonded windows ensures appropriate chemical
compatibility for the application. Furthermore, to
ensure optimum UV/Vis or NIR spectroscopic
absorption features for analysis, optical
transmission pathlengths are available from 1.0 to
10 mm. Optical components within the cell are
selected to be compatible with the wavelength
range of interest and the diameter of optical fiber
specified by the user. Optical fiber connectivity
is ensured by industry standard SMA 905
connectors.
ProCell Vortex:
Reliability, for peace of mind
All aspects of the ProCell Vortex were developed
to give long-term reliability under the tough
conditions of thermal shock, high operating
temperatures, and aggressive chemistries that
are often encountered in the process
environment. The use of sapphire windows gives
outstanding abrasion and chemical resistance,
in addition to the ability to withstand severe
thermal shock (e.g. plant cleaning with high
pressure steam).
The Specac ProCell Vortex can be designed with
a proprietary dual seal arrangement to give
proven long term reliability (with examples of the
cell in continuous use for 15 years). Special
“hoods” are included that fit over the optical fiber
connectors and give environmental protection
(keeping out water, dust and dirt) as well as
physically supporting the cable outer sheath or
armouring. The latter ensures that stresses from
the weight of the cable (or from it being moved,
pulled, etc.) are not transmitted to the optical
fiber connection interface.

ProCell Vortex:
Enhanced Optional Features
Cleaning Ports
An attractive feature of the Specac ProCell Vortex
process cell is the optional “cleaning port”, where
a novel plug arrangement gives access to the
window surfaces. This allows the internal cell
windows to be cleaned without removing the cell
from the pipe work, in the event that fouling
occurs (either from long term use or following a
process upset that caused material to be
deposited within the plant). To assist this
functionality, the cell would typically be installed in
a ‘by-pass’ loop where valves can isolate it from
the main process when servicing occurs.
‘Tell-tale’ Ports
A further propriety optional feature is the ‘Tell-
Tale’ ports. These are small passages within the
cell body that link the space between the primary
and back-up window seals to an outside port.
They can be used in critical or hazardous
applications in several ways: either as a visual
indication of leakage from the primary seal, or
with the use of a secondary detection system in
the event of a particularly hazardous material. If
leakage is observed the user has the option of
dealing with it immediately or fitting a blanking
plug into the port. The latter has the effect of
stopping the leak and allowing the process to
pressurise the secondary seal. The user is then
aware that the cell is operating on the back-up
seal and needs attention at the first convenient
opportunity.
Diffusion Bonding
Versions of the Specac ProCell Vortex process
cell are available with diffusion bonded windows.
These versions avoid the use of any polymer
materials and are capable of operation at
temperatures up to 400°C or in chemical
environments that are incompatible with even
the high performance perfluoroelastomer seals.
